Using Student Space Assets For Atmospheric Science Research

1. Using Student Space Assets For Atmospheric Science Research NSF Workshop for Small Satellite Missions For Space Weather and Atmospheric Research George Mason University Arlington, VA May 17, 2007 Professor Bob Twiggs, Director Space and Systems Development Laboratory Stanford University

2. Overview • Student satellite programs • Commercial – off the shelf satellites • Training students to do satellites • Future student space programs • Summary

3. Leave Message for Today • Student satellite program are more mature than you may expect and will continue to advance rapidly. • Collaboration is the fuel of success. • Small Satellite Missions: • Educate students in engineering & science • Produce innovation • Tests new technology • Are doing real science at low costs

29. Future Student Programs?

30. There will be a private funded • Student Lunar Spacecraft Launched before • End of this Decade

32. Summary

33. Status of Student Programs? • Successes - really low costs • Successes - despite no direct space industry support • Getting launches despite US launch industry • Bus technology maturing • Soon – complete commercial CubeSat bus • Get experience in building, integration, ops • Make a contribution with new technology • Increased interest in scientific missions

34. Message to you today: • NSF – Universities • Make a Deal Today!

35. Thanks

36. CubeSat science payloads • Instrument component space qualification • Common secondary payload on all CubeSats • Radiation sensor • Magnetometer • Tethered satellites for constellations • Tethers for spaced sensors • How do we match scientists to spacecraft developers? • Have universities test spacecraft bus on sounding rocket • with science instruments?
